"A new analysis of licensing data shows that not only is use of the GPL and other copyleft licenses continuing to decline, but the rate of disuse is actually accelerating." This shouldn't be surprising. The GPL is complex, and I honestly don't blame both individuals and companies opting for simpler, more straightforward licenses like BSD or MIT-like licenses.

Can't be bothered wading through six pages of comments, but just in case no-one else posted it; this is not 'new', it's four months old.

The most important point made at the time is that use of the GPL is not actually declining. It's just growing at a slower rate than use of BSD-style licenses, in the set of projects covered by the survey.
